T0 to whom, it may concern.-

I, Be it known that 1, DAVID E. PHILLIPS, a citizen of the United States, residing at Mahanoy City, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Dust Guards or Armors for Cars, of which the following is a specification.

The object of myinvention is to provide a device which may be arranged between the windows of a passenger-car for the purpose of deflecting dust and cinders, so that they will not enter the window. Another function of the device is to deflect the air from the window-pane, so that frost will not form there= on in cold weather. The device is arranged so as to afford as little resistance as possible to the air during the movement of the train, and it is operative when the car is traveling in either direction.

In the accompanying drawings, which illustrate my invention, Figure l is a view of a portion of a car-body, showing several of my improved deflecting devices in position. Fig. 2 is a perspective view of a complete deflecting device. Fig. 3 is a similar'view of the device with the guard removed, and Fig. 4 is a similar view of the guard which surrounds the deflectors.

The deflector may be made in one piece of cast metal, or it may be made of stamped sheet metal in whole or in part. I prefer, however, to make the device as shown in the drawings, in which A represents a strip of wood which is of sufficient width to extend between two of the Window-frames of a car and is somewhat longer than the movable sash. The upper end B of the strip is formed with an ogee or other suitably-inclined molding, as shown, so that cinders will not rest upon it, and for the sake of symmetry the lower end 0 is similarly formed. Between its upper and lower'ends the strip is formed with a series of triangular projections D, extending across the strip and having their faces inclined from the apexes to the bases, as shown, and aseries of inclined triangular projections E, formed between the projections D and having their apexes at the opposite side of the strip from the apexes of the projections D and their faces inclined in the opposite manner. These projections are formed by saw ing the strip in a Zigzag manner at angles of about seventy degrees to the sides to form the triangles and then beveling the face of each triangle from its apex to its base, the result being a series of deflector-faces, which are alternatelyinclined and tapered in o'ppo; site directions, with the slot or saw-kerf F separating the adjacent projecting deflectors. Within the saw-kerfs I arrange a guard G, consisting of a strip of sheet metal which is bent into a zigzag shape, so as to extend around the sides of the projecting deflectors, as shown in Figs. 1 and 2. The width of the strip is equal to the depth of the apexes of the deflectors, and the straight parts of the strip between adjacent deflectors form guards, which confine the dust striking the face of the deflector and guide it to the apex.

When the device is placed upon a car, it will be seen that if the car moves in the direction indicated by the arrow, Fig. 1, the cinders, dust, &c., which ordinarily would pass into the window at the left of the device will strike the deflectors E and be thrown off at the apexes. On the other hand, if the motion of the car be reversed the cinders, 850., will strike the deflectors D and be guided by the guard to the apexes and there thrown off. It will also be noted that by means of the deflecting device the current of air passing the car-window, caused by the movement of the train, will be broken, so that in winter-time the accumulation of frost upon the Windowpane will be largely prevented.

The metal guard G may be a strip of plain sheet metal, or it may be in the form of a screen, as indicated in the lower part of Fig. 2, so as to ofier as little resistance to the air as possible. may also be formed in various ways and of different materials, such as stamped sheet metal or castings. When arranged upon a passenger-car, the outermost part of the deflectors will not project beyond other overhanging parts of the car. They are therefore free from interference with objects along the track, the frictional resistance causedby their passage through the air is negligible, and their appearance is rather ornamental than otherwise. The device is intended to fill the entire space between the window-frames, thus taking the place of the usual panel and also As previously stated, the device bringing the apexes of the deflectors as close as possible to the windows.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A dust and air deflector for cars consisting of a panel adapted to extend between two car-windows, and having on its outer side a series of transversely-arranged deflectors,said deflectors being alternately inclined and tapered in opposite directions, and having their apexes located at the sides of the panel adjacent to the windows, and a guard extending outwardly between the adjacent deflectors, substantially as described.

2. A dust and air deflector for cars consisting of a panel adapted to extend between two car-windows, and having on its outer side a series of transversely-arranged defiectors,said deflectors being alternately inclined and tapered in opposite directions, a saw-kerf or slot between the adjacent deflectors and a guard arranged in said kerf and projecting outwardly to approximately the same distance as the points of the deflectors.

In testimony whereof I afflx my signature in presence of two Witnesses.
